Answer 1

While @einterview's answer is almost correct, it's important to note that a * in the minute column will run the job every minute of that hour. If intending to run once every hour, steps would be:

1. SSH into server.

2. Get list of current user's jobs with $ crontab -l

3. Edit jobs list with $ crontab -e (default editor will open)

4. Add 0 4 * * * service mysql restart for mysql at 4:00am

5. Add 0 5 * * * service apache2 restart for apache2 at 5:00am

6. Add 0 0 * * * service apache2 restart for apache2 at 12:00 am

7. Save and close (Ctrl+O and Ctrl+X in nano)

8. Recheck with $ crontab -l
